LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 515,404, dated February27, 1894.

Applicationfiled August 5,1893- Serial No. 482,419. (ModeL) To all whomit may concern:

Be it known that I, LOUIs MERTENS, a citizen of the United States,residing at Erie, in the countyof Erie and State of Pennsylvania,haveinvented certain new and useful Improvements in Lubricators; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention relates to lubricators and particularly to such as areused for lubricating the crank pins of steam engines or carried by themovable parts of machines of various kinds, and wherein the oil isagitated by the reciprocating or other action of the part to which thelubricator is attached.

My invention consists in the construction and combination of parts aswill be hereinafter fully described and pointed out in the claims.

The invention is illustrated in the accompanying drawings as follows:

Figure l is a vertical central section view. Fig. 2 is an elevation viewof the cap and parts carried thereby, detached from the cup. Fig. 3 is atransverse section on the line 2-2 in Fig. 2. Fig. 4 shows a modifiedconstruction of the parts carried by the cap, the same being in verticalsection.

A marks the cup body; a, its attaching stem; (1' its discharge opening;A the contained discharge tube; B, the cap or screw plug which closesthe top of the cup; B a deflecting cone formed on the lower end of theplug; 1), hangers attached to the plug which supports the tube-cover, C;b wings or partitions extending from the hangers b to the cone B; O, adisk which forms a cover for the tube A; G, a sleeve extending down fromthe disk and over the tube A; c, an opening through said disk; D, adiaphragm held within said opening a; d, a drip hole in said diaphragm;d the drip opening in the disk 0, when as in Fig. 4.

In this class of lubricators the oil, when agitated by the reciprocal orother movement of the cup, is thrown up against the top of the cup, andmeans are provided for directing a part of the oil into the dischargetube which extends above the main body of oil.

Various devices for directing the oil into the discharge tube have beenprovided, and my invention consists primarily in improved means for thispurpose.

One of the leading features of my invention consists in having all themeans for catching the swashed-up oil and conveying the proper amountthereof into the discharge tube connected to and removable with the capor plug, B. This is not broadly new, as will be seen by reference toLetters-Patent No. 86,540, issued to D. Harrigan February 2,1869, onwhich construction my invention maybe considered as an improvement.

The construction of my device is as follows: The cup or shell A, may beof any desired material or form, but as shown it is made of cast metal,such as brass, and is elliptical or egg-shapedwhich shape is especiallydesirable, particularly in the upper portion,as it directs the swashingoil toward the center of the cup at the top; but this feature is not newwith me, as it is shown in Letters- Patent No. 239,461, issued to S. W.Davis March 29, 1881. The means for attaching the cup, to wit, the screwshank a, is common in cups of this character; and the attaching means isimmaterial as it forms no part of my invention. The cap or plug B, ispreferably screwed into the cup shell, and on its lower face is adepending cone B, which may be made plain as in Fig. 1, or fluted as inFigs. 2 and 3. This cone is made so that, when the plug is screwed downto place, the edge of the base of the cone is just even with the top ofthe cup so that the surface of the cone forms a continuation of theswash or dash lines of the sides and top of the cup, and so it serves asa deflector and directs the swashed up oil which comes in con tact withit directly down ward at the center of the cup. Directly below the coneis a disk 0, supported from the plug by hangers, b. If desired thehangers may be extended inwardly so as to intersect or connect with thecone, thus forming deflecting wings, 19 as shown in Figs. 1 and 4. Theobject of channeling the cone, either by means of flutes as shown inFigs. 2 and 3, or by wings as shown in Figs. 1 and 4, is that the swashof the oil is deflected and its force concentrated by the convergingsides of the channels toward a central point, at which point in mydevice is the drip opening. This result is of course, much moreeffectually ac complished by the use of the wings as they make muchwider and deeper channels and catch and deflect a much greaterproportion of the oil as it is swashed against them, hence I prefer thisconstruction.

Connected with the disk 0, and depending from it, is a sleeve 0', whichextends down over the discharge tube A. This sleeve entirely preventsoil from gaining access to the tube A, except through the providedopenlng for the purpose.

In Fig. 4 I show the disk 0 provided with a small opening, 01', directlyunder the apex of the cone. Such a construction is suflicient exceptwhere it is desirable to vary the size of the opening to suit thefluidity of the oil used or the amount of oil necessary to be consumed.To allow for such variation I pro vide a changeable diaphragm D, whichis secured in the disk at the upper end of the sleeve, 0', in which casethe disk is provided with a large opening 0, opposite the apex of thecone, the diaphragm D closing said openmg and being provided with asmall opening (1.

The users of my cups will be provided with several diaphragms for eachcup, and these will have openings, 01, of varying size, and the user caninsert in the cup a diaphragm having an opening of the proper size topass the proper amount of oil.

In all devices of this kind with which I am acquainted wherein there isa cover for the discharge tube in which is a drip opening (properly socalled) the cover is supported by the discharge tube. By attaching thiscover to the plug, it is always removed from the cup with the plug, sothat it can be readily examined and cleaned. This construction isparticularly advantageous where a drip opening is used, because being somuch smaller than the discharge tube, it forms the only place in thedischarge passage liable to become stopped. When the cover with thissmall opening is attached to the discharge tube and the cup is in placeon a hearing, it is impossible to see whether it is stopped or not. Whenit'is attached to the plug, as in my device, and is removed with theplug, it has the light on both sides of the opening, so that it can bereadily seen whether or not the opening is stopped. This construction isalso particularly advantageous in connection with the removablediaphragm in which is the drip opening, as the position of the top ofthe tube with relation to the surrounding cup is such that it would bemuch more difficult to rewardly deflecting cone at the top of said cuphaving channel's formed by wings orplates extending radially fromthesurface of the cone and converging atthe apex of said cone, said apexbeing above said tube for the purposes set forth.
